earlier today while beeing locked in to my girlfiends wifi I played some music from my android phone to her sonos system.
Now a few hours later I'm at the other side of town locked into my wifi. Sitting in front of my windows system at my place I still can send music to her speakers. I scared the **bleep** out of her with some dodgy eurodance trash blasting out of her kitchen on full volume. She wasn't as amused as I was when she called me afterwards...
I think this is a big security issue and should be adressed imediately.
